Pallet assembly

ABSTRACT

A pallet assembly is composed of multiple pallet pieces and multiple wedging elements. Each pallet piece has four corners with four individual legs and multiples engaging holes defined on sides of the pallet piece. Each leg is rectangular in transversal cross-section and selectively has a mortise or a tenon to detachably and engages with other corresponding leg on an adjacent stacked pallet piece in the pallet assembly. Moreover, each wedging element is clamped between two adjacent juxtaposed pallet pieces to widen the pallet assembly. Thereby, the pallet assembly is versatile in changing sizes, easy to be assembled and disassembled, stable in use and convenient in storage.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a pallet assembly, and moreparticularly to a pallet assembly comprising multiple pallet pieces andmultiple wedging elements easily and selectively combined together tomake the pallet assembly stable in use, flexible in size and convenientin storage.

2. Description of Related Art

Pallet is used to provide transportation convenience for stacked goodson the pallet by spacing the stacked goods from the ground so that alift truck can rapidly move the stacked goods with the pallet together,especially when the stacked goods are in huge numbers. For industrialoperation, the pallet must be changeable in sizes and easily assembledin practice.

With regard to structure of a conventional pallet commonly seen inpresent, the conventional pallet has a one-pieced structure with aregular size after the conventional pallet is manufactured so that areafor stacking goods on an individual conventional pallet is unchangeable.Therefore, the individual conventional pallet can not be enlarged toprovide more area for stacking more goods. On the contrary, it isimpossible to be diminished to correspond with insufficient storageroom. Therefore, the conventional one-pieced pallet having the regularsize is not flexible in use.

Additionally, another conventional pallet has a combination structurecomposed of multiple units that are modified for improvement ofmanufacturing process not for size variation. Therefore, use efficiencyof the conventional pallet having the combination structure is the samewith the former one and the same drawback has not been overcome yet.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a palletassembly that comprises multiple pallet pieces and multiple wedgingelements to selectively and conveniently combine together to performdifferent variations and then to correspond different requirements foruse.

To achieve the foregoing objective, the pallet assembly comprises:

multiple pallet pieces, each pallet piece being a rectangular board withfour sides and four corners and having four legs individually formed atthe four corners and multiple engaging holes defined on each of the foursides; and

multiple wedging elements attached between adjacent two of the multiplepallet pieces, each wedging element having two ends respectivelycombined to aligned two of the multiple engaging holes on the adjacenttwo of the multiple pallet pieces.

Further benefits and advantages of the present invention will becomeapparent after a careful reading of the detailed description withappropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A pallet assembly in accordance with the present invention comprisesmultiple pallet pieces and wedging elements. Each pallet piece has fourcorners with legs and multiples engaging holes defined on sides of thepallet piece. Each leg is rectangular in transversal cross-section andselectively has at least one mortise or at least one tenon to detachablyand engages with other corresponding leg on an adjacent pallet piecestacked thereto in the pallet assembly. Moreover, each wedging elementis clamped between two adjacent juxtaposed pallet pieces to widen thepallet assembly. Thereby, the pallet assembly is versatile in changingsizes, easy to be assembled and disassembled, stable in use, andconvenient in storage.

With reference to FIGS. 1, 2 and 5, a pallet assembly 10 in accordancewith the present invention comprises multiple pallet pieces 1 andmultiple wedging elements 2.

Each pallet piece 1 is a rectangular board with four legs 111respectively formed at fours corners and has multiple engaging holes 12evenly defined on sides of the rectangular board. Each leg 11 on thepallet piece 1 is composed of four blocks each having a distal end and atenon 111 or a mortise 112 alternatively formed at the distal end (asshown in FIG. 3).

Each wedging element 2 is a double-headed stick having a middle flange21 and two resilient forks with enlarged heads 22 that make the wedgingelement 2 secured on the pallet piece 1 when the resilient forksrespectively penetrate two corresponding engaging holes 12 on twoadjacent juxtaposed pallet pieces 1. Moreover, the flange 21 keeps thewedging element 2 from entirely passing through the engaging holes andpositions the pallets pieces 1 with the enlarged head 22 aftercombining. Therefore, the combined juxtaposed pallet pieces are keptfirm together without separation by simply using the engaging element 2.As shown in FIG. 5, the pallet assembly 10 can be widened to carry moregoods thereon.

By having the structure of the pallet piece 1, the goods enable to belocated on a top face of the pallet piece 1 because the pallet piece 1has multiple legs 11 on a bottom face. Two pallet pieces 1 arejuxtaposed closely and combined together by inserting two wedgingelements 2 into the corresponding engaging holes 12 at adjacent sides onthe two pallet pieces 1 (as shown in FIG. 4) to elongate the palletassembly. Moreover, four pallet pieces 1 can be arranged into a squareto enlarge the pallet assembly 10 and combined by the wedging elements 2in the same manners to accord with different lift trucks. Selectively,multiple pallet pieces 1 can be arranged into an L-shape to accord toirregular storage space.

Additionally, the pallet assembly can be varied in height as shown inFIGS. 3 and 6. The legs 11 having mortises and tenons on one palletpiece 1 correspondingly combine other legs 11 on an adjacent palletpiece 1 by matching the mortises and the tenons as shown in FIG. 6.Therefore, the pallet assembly performs a double-sided structure and isheightened (thickened) to become strengthened to stably support heavystacked goods. When the ground is muddy or uneven, the pallet assemblyhas the double-sided structure can provide more abutting area (more thanthree-fourths or two-thirds of the face) on a lower pallet piece tocontact and firmly grip the ground so that stability of the palletassembly is improved.

According to above description, the pallet assembly in the presentinvention has the following advantages:

1. The pallet pieces 1 are conveniently and flexibly assembled togetherin different shapes to make the pallet assembly versatile to correspondwith different requirements of the stacked goods or storage room.

2. When the pallet pieces 1 are combined with legs to legs, the palletassembly 10 can be strengthened to stably support heavy goods stackedthereon.

3. Each pallet piece 1 of the pallet assembly is much smaller than theconventional pallet having the one-pieced structure. When the palletpiece downsizes, module cost for manufacturing the pallet piece issignificantly diminished since the size of the module positively relatesto the module cost. Moreover, the diminished pallet piece 1 is easy tobe transported or stored and flexible in use.

Although this invention has been described in its preferred form with acertain degree of particularity, it is understood that the presentinvention of the preferred form has been made only by way of example andthat numerous changes in the details of construction and the combinationand arrangement of parts any be resorted to without departing from thespirit and scope of the invention.
